I think that maybe this thread underestimates some of the reasons that dividends are good.
A company which pays dividends is making cash to pay them. A stock price isn't real cash, it will rise or fall based on expected future growth - if a company like Tesla were paying a dividend, then markets tend to understand that as Tesla saying "we are pretty sure we can keep paying this amount indefinitely into the future, and still fund whatever new shit we want to do". Dividends are hard promises that require real earnings to back them up.
For an individual investor, it's nice for us if companies turn around and invest their excess cash in things that generate returns (for both tax and simplicity reasons). But for a giant institutional investor, they might have better places to invest that excess cash outside of a company (maybe they don't think Coke needs to expand any further, but there's big growth in renewable electricity - Coke might not be able to capture those returns but someone else certainly can).
In a general way, I see a company which is paying a dividend as a company that's actually making money today (alternately, they might be a company that's borrowing money to pay a dividend, which is probably terrible). They're not betting so hard on future growth that they're denying today's earnings. That appeals to me, and I think it also helps align incentives better rather than requiring a 'growth at all costs' model.
To link it to the comments about the future - dividends are a demonstration by a company that their current performance actually matches the future they're trying to sell you on.
The flipside is high-dividend companies (excluding REITs and MLPs) are companies which are out of ideas to productively reinvest their earnings. Their best and brightest leadership cannot figure out a way to earn their cost of capital from new investments. New products won't work. Expansions to new markets won't work. Efficiency investments won't work. Therefore, it makes sense to send the funds back to investors so that they can invest in companies that do have some potential left. Dividends are a way of winding down a past-its-prime company over the course of decades.
The whole "commitment" to dividends custom is Not A Good Thing. First, it creates a cash-draining obligation that is indifferent to what's going on inside the company. First Republic Bank was paying dividends even as their asset portfolio was being decimated and they went under 4 months after their last dividend, IIRC. Lots of other companies are paying 6-8% to borrow money in one hand, and paying out a 3-4% dividend from the other. Does that sound like a good investment? Second, it creates a cash-draining obligation that is indifferent to things going on outside the company. For example, interest rate changes, stock market corrections, liquidity crunches, and available opportunities are constantly occurring. A company committed to dividends cannot deleverage as quickly when interest rates rise, cannot buy assets when they go on fire sale, cannot raise the funds to raise their credit rating and save tons of money on interest, and cannot jump on internally-generated opportunities such as new inventions or product ideas.
At some point in the not too distant past, the financial zeitgeist about saving and spending among retirement gurus morphed into another even stranger duck—called a Safe Withdrawal Rate. This silliness posits that the retiree-in-training adopts a religious belief that past market performance is indicative of future returns and times his spending over decades so he dies after spending his last nickel. (You can’t make this shit up LOL!)
I believe most “real” retirees actually spend closer to the dividend+interest philosophy than the vaunted 4% SWR prayer group prefers but the reigning woke intelligencia makes the former approach seem like the tool of the uneducated.
So anyway, YES, there is nothing wrong in living off interest and dividends if you’re fine with the that amount of money. It is pretty much what I do, for the most part, although I have set some funds to reinvest too. But don’t buy into the game, thinking that you can’t touch principal or reinvest some of your returns during retirement. Don’t think dividend stock are better or worse than others and certainly don’t buy funds comprised of that group of companies!
It’s better to think about spending at a low WR level than to think of “living off dividends”.
I believe you're defending a cash income model as opposed to a SWR / X% rule model, even though you are suggesting people "think about spending at a low WR level" rather than dividend income.
A lot of landlords in particular have a too-high WR compared to their equity and yet can demonstrate they're generating plenty of inflation-indexed income to cover their needs. Similarly, people with significant pensions, annuities, or side gigs find it easier to think in terms of what additional income they need rather than in terms of WRs.
The pitfall with applying an income replacement model to a portfolio containing stocks is that stock prices are highly variable and dividends are never guaranteed. The problems happen in years when dividends are cut, forcing one to sell more shares at a fraction of their previous values, reducing the future dividend stream.
Stocks do not provide a reliable income, and reliability is a prerequisite to apply an income replacement model.
Less-reliable income sources like stock/bond portfolios are more appropriately assessed with a SWR model. Such a model can take into account future uncertainty and can output the historically-informed probability of portfolio survival at various WR decisions. Plus, a SWR model can easily account for reliable sources of cash income and output the necessary WR or portfolio size numbers based on the difference, and at one's desired level of risk. Similarly, SWR analysis can allow one to specify one's expected terminal age or assess the odds of leaving an inheritance.
The income model has its issues too. Lots of income sources are not adequately inflation-indexed. Some are deteriorating assets such as rental units in neighborhoods that might decline. Pensions and even certain safe bonds have a failure rate. It seems bold to forecast their returns over 30-40 years. Stock/bond portfolios, in contrast, are more diversified.
